I had the same experience with the Galaxy Nexus. I literally threw it onto the road....twice. Both events happened while running with the phone in my hand. The first time I threw it downwards at speed, the second time I launched it about 10 feet in front of me. The back and corners took some dents and chips, but no significant damage.

I've not been particularly fond of LG hardware since a friend had an LG device spontaneously catch fire.
